Objective To investigate the expression of centromere protein-C （CENP-C） in villus tissue of the first-trimester spontaneous abortion （SA） and the correlation study of CENP-C expression with chromosome segregation. Methods Fluorescence in situ hybridization （FISH） and G-banded karyotype analysis were used to detect the numerical chromosome abnormality in 94 villus tissues of women with SA. The participants were separated into case group （n=30） and control group （n--30） according to the results with FISH. The qRT-PCR and Western blotting analysis were used to assess the expression level of CENP-C. Results Forty-eight （51.06%） cases had observed the numerical chromosome abnormality, including 30positive cases and the positive rate was 31.91%. The main types of variation included trisomy 16, 21, 22, X monosomy and triploid. The expression levels of CENP-C mRNA and protein in case group were statistically higher than that in control group （P〈0.05）. Conclusion Expression of CENP-C in the villus tissues of women might be related to SA induced by chromosomal aneuploid.

Mononuclear macrophage infiltration in the central nervous system is a prominent feature of neuroinflammation. Recent studies on the pathogenesis and progression of multiple sclerosis have highlighted the multiple roles of mononuclear macrophages in the neuroinflammatory process. Monocytes play a significant role in neuroinflammation, and managing neuroinflammation by manipulating peripheral monocytes stands out as an effective strategy for the treatment of multiple sclerosis, leading to improved patient outcomes. This review outlines the steps involved in the entry of myeloid monocytes into the central nervous system that are targets for effective intervention: the activation of bone marrow hematopoiesis, migration of monocytes in the blood, and penetration of the blood–brain barrier by monocytes. Finally, we summarize the different monocyte subpopulations and their effects on the central nervous system based on phenotypic differences. As activated microglia resemble monocyte-derived macrophages, it is important to accurately identify the role of monocyte-derived macrophages in disease. Depending on the roles played by monocyte-derived macrophages at different stages of the disease, several of these processes can be interrupted to limit neuroinflammation and improve patient prognosis. Here, we discuss possible strategies to target monocytes in neurological diseases, focusing on three key aspects of monocyte infiltration into the central nervous system, to provide new ideas for the treatment of neurodegenerative diseases.

Investigating the damage and ignition behaviors of polymer-bonded explosive(PBX) under a coupled impact and high-temperature loading condition is required for the safe use of charged PBXs. An improved combined microcrack and microvoid model(CMM) was developed for better describing the thermal effects of deformation, damage, and ignition responses of PBXs. The main features of the model under typical dynamic loadings(i.e. uniaxial tension and compression, and lateral confinement) at different initial temperature were first studied. And then the effects of temperature on impact-shear sensitivity of HMX-based PBXs were investigated. The results showed that the ignition threshold velocity of shear-crack hotspots exhibits an increase from 260 to 270 to 315-325 m/s when initial temperature increases from 301 to 348 K;and then the threshold velocity decreases to 290-300 m/s with the initial temperature continually increasing to 378 K. The predicted ignition threshold velocity level of the explosives under coupled impact and high temperature loading conditions were consistent with the experimental data.
